Recommended: Signature encryption for Android APK

See good technical tutorials just want to reprint, do not like to spray! Thanks for the cooperation, only for rookie study study, do not do bad oh \ (^o^)/~

1. Encrypt apk.

Here I'm using love encryption from the project Bin directory under copy apk file upload to love encrypted website encryption while downloading the signature tool. can refer to http://jingyan.baidu.com/article/925f8cb8151347c0dde0563d.html

2. Generate the signature apk Keystone

1) Generate keystone in eclipse (typically a keystone for an apk file, after the release of the software, the release of the upgrade apk must use the same keystone to sign the APK will not be prompted to update)

Select Items Right-click->android tools->export signed Application package, fill in the password and keep the password. Once lost, the APK will not upgrade, location represents the current generated key storage path

Then follow the prompts to fill in the information step-by-step.

2) If you have already generated a Keystone file, such as the APK to export the signature, select the Use existing Keystone and enter the password to export.

3. After signing the encrypted apk

Get the encrypted apk and the current apk corresponding to the generated Keystone Post-open signature tool: Enter the APK path, Keystone Path, password Click Start encryption OK

The version after the last encrypted signature is the one that can be published.

"Note" The currently generated Keystone file can be used to sign any apk file, like a writer's signature, but also must keep the Keystone file and password to regenerate the Keystone file will be different from the original program is unable to upgrade.

There is a question do not know the signature after the encryption and encryption after the signing of what difference, who if know the trouble to tell me under!
